Laser with a Subwavelength Hole Array in Metal Film
Researchers at Purdue University have developed a design of a two-dimensional laser device using subwavelength hole arrays in metallic thin film. Lasers with this design can work at room temperature and operate in the visible wavelength regime with unidirectional propagation. Lasing performances can be adjusted by varying the dimensions of the periodic holes. This design also allows for lasing with low threshold and high efficiency.
